Hello Sakshi, Under such situation try to submit through other Bank or another branch... submit the Challan to nearest ICICI Branch and deposit fee in ICICI bank. There is no need to have an account in that bank/branch. The bank teller will verify the details printed on the challan with the data available at the bank and then accept the payment. The bank will retain one copy and give back another copy to the candidate which he/she has to retain for reference.

This will help...

Secondly, you can try to pay online by using another browser... 

Lastly, you can refill the form and make online payment before 31st march 2018

For further assistance be free to contact... All the Best
